Question

calculate the volume of oxygen at 15°c and 745mmHg pressure which could be obtain by heating 10g of potassium trioxochloride.
(molar volume at stp is 22.4dm3. K = 39, Cl = 35.5 O = 10)
2KClO3 ==> 2KCl + 3O2

mols KClO3 = grams/molar mass = ?
mols O2 generated = mols KClO3 x 3/2 = ?
Use PV = nRT to solve for V in liters.
Post your work if you get stuck
Why do you think the right method of approach should be the ideal gas equation? Don't you think the right method of approach should be a mix of mass-volume relationship with general gas equation?
